ℹ️ Here's how to fix them:

• Fix typos: Open the relevant files and fix any identified typos.
• Update wordlist: If a flagged word is actually a project-specific term add it to wordlist.txt in the project root. Each word should be listed on a separate line. Learn more.
• 🚧 Remember:
  • When adding new words it MUST NOT have any spaces or special characters within or around it.
  • wordlist is NOT case sensitive.
  • Use backticks to quote code variables so as to not bloat the wordlist.
